Backpack with an elastic breathable fabric

ABSTRACT

A backpack with an elastic breathable fabric contains a body and an elastic breathable fabric. The body includes an outer surface, a back surface, at least one strap connected with the back surface, a receiving space defined between the outer surface and the back surface, and a contacting portion formed on a central position of the back surface. The elastic breathable fabric, is formed in a mesh shape, has a pre-set tension, and is fixed on the contacting portion of the back surface of the body. Also, the elastic breathable fabric includes a plurality of tiny holes so that the elastic breathable fabric communicates with the receiving space. Thereby, when the elastic breathable fabric contacts with the user&#39;s back, it provides breathable wicking function. Also, the elastic breathable fabric has the pre-set tension to recover elasticity quickly, thus reducing carrying pressure to user&#39;s body.

FIELD OF THE INVENTION

The present invention relates to a backpack, and more particularly to abackpack with an elastic breathable fabric which obtains breathableperspiration, enhances comfort, and reduces carrying pressure.

BACKGROUND OF THE INVENTION

Conventional backpack with a fixed breathable member is disclosed in TWPat. No. 099224480 and contains a body. The body includes a back surfaceand two carrying straps mounted on the back surface; two weave strapssewed with the two carrying straps of the body, wherein each weave straphas a connector and a buckle so as to adjust its tightness and length;four flexible pads covered on the back surface of the body; at least onelocking assembly defined between the two weave straps so as to fixuser's chest and waist.

However, the four flexible pads contact with the user's back, thuscausing poor ventilation and sultriness.

Another conventional backpack with a removable breathable member isdisclosed in US publication No. 2011/0284608A1 and contains aventilation zone arranged on a rear side of the backpack, and theventilation zone has a positioning rack and a breathable mesh fabricmounted on the rear side of the backpack and has two carrying strapsconnected with the ventilation zone. The breathable mesh fabric has twosupporting corners defined on an upper side thereof so as to supportuser's shoulder and separating apart from the positioning rack so thatthe rear side of the backpack keeps a distance from the user's shoulderand buttock. Likewise, the breathable mesh fabric is arranged to provideventilation cooling effect. Nevertheless, such a breathable mesh fabrichas complicated structure, and the upper side of the backpack supportsthe user's shoulder by using the two supporting corners and a lower sideof the backpack supports the user's buttock, such that support pointsgenerates on the upper side and the lower side of the backpack, so theuser's back cannot support and carry the backpack properly, thus havingusing comfort and carrying pressure to the user's body.

The present invention has arisen to mitigate and/or obviate theafore-described disadvantages.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a backpackwith an elastic breathable fabric which obtains breathable perspiration,enhances comfort, and reduces carrying pressure.

To obtain the above objectives, a backpack with an elastic breathablefabric provided by the present invention contains: a body and an elasticbreathable fabric.

The body includes an outer surface, a back surface, at least one strapconnected with the back surface, a receiving space defined between theouter surface and the back surface, and a contacting portion formed on acentral position of the back surface.

The elastic breathable fabric, is formed in a mesh shape, has a pre-settension, and is fixed on the contacting portion of the back surface ofthe body. Also, the elastic breathable fabric includes a plurality oftiny holes so that the elastic breathable fabric communicates with thereceiving space.

Thereby, when the user carries a backpack on his/her back by ways of theat least one strap, the elastic breathable fabric contacts with theuser's back and it communicates with the receiving space of the body,thus obtaining breathable perspiration.

Furthermore, the elastic breathable fabric is fixed on the contactingportion of the back surface of the body and communicates with thereceiving space to achieve breathable effect. Accordingly, when theelastic breathable fabric contacts with the user's back, it providesbreathable wicking function.

Also, the elastic breathable fabric has the pre-set tension to recoverelasticity quickly, thus reducing carrying pressure to the user's body.

Preferably, the elastic breathable fabric is sewed, glued, hot melted,or high-frequency welded with the contacting portion so as to simplifymanufacture process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring further to FIGS. 1-4, a backpack with an elastic breathablefabric according to a preferred embodiment of the present inventioncomprises: a body 10 and an elastic breathable fabric 20.

The body 10 is comprised of an outer surface 11, a back surface 12, atleast one strap 13, a receiving space 14 defined between the outersurface 11 and the back surface 12 and used to receive objects, and acontacting portion 15 formed on a central position of the back surface12 and having two breathable clothes fixed on two sides of thecontacting portion 15. The at least one strap 13 is connecting with anupper side and a lower side of the back surface 12.

The elastic breathable fabric 20, is formed in a mesh shape, has apre-set tension, and is fixed on the contacting portion 15 of the backsurface 12 of the body 10. The elastic breathable fabric 20 includes aplurality of tiny holes so that the elastic breathable fabric 20communicates with the receiving space 14. Also, the elastic breathablefabric 20 is sewed, glued, hot melted, or high-frequency welded with thecontacting portion 15 so as to simplify manufacture process.

Thereby, the body 10 includes the connecting portion 15 formed on thecentral position of the back surface 12, the connecting portion 15 isconnected with the elastic breathable fabric 20, and the elasticbreathable fabric 20 communicates with the receiving space 14 of thebody 10 so as to obtain breathable effect. In addition, the elasticbreathable fabric 20 has the pre-set tension so as to reduce carryingpressure to a user's body and to achieve using comfort.

In assembly, the outer surface 11 is coupled with the back surface 12 soas to form the body 10, and the back surface 12 of the body 10 has theconnecting portion 15 formed on the central position thereof, thusfinishing the assembly.

In operation, the user carries a backpack on his/her back by ways of theat least one strap 13, so the elastic breathable fabric 20 contacts withthe user's back and it communicates with the receiving space 14 of thebody 10, thus obtaining breathable perspiration.

Furthermore, the elastic breathable fabric 20 is fixed on the contactingportion 15 of the back surface 12 of the body 10 and communicates withthe receiving space 14 to achieve breathable effect. Accordingly, whenthe elastic breathable fabric 20 contacts with the user's back, itprovides breathable wicking function. Also, the elastic breathablefabric 20 has the pre-set tension to recover elasticity quickly, thusreducing carrying pressure to the user's body.

Preferably, the elastic breathable fabric 20 is sewed, glued, hotmelted, or high-frequency welded with the contacting portion 15 so as tosimplify manufacture process.

While the preferred embodiments of the invention have been set forth forthe purpose of disclosure, modifications of the disclosed embodiments ofthe invention as well as other embodiments thereof may occur to thoseskilled in the art.
